SAMUEL K. DUNKLE, or SHARON, PENNSYLVANIA;

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 734,835, dated July 28, 1903.

Application filed January 13, 1903. Serial No- 138,903. (No model.)

To will whom it may concern.- Be it known that I, SAMUEL K. DUNKLE, of

. Sharon,in the county of Mercer and State of Pennsylvania, have invented a new and use{ used, and has for its object to provide a linkless car coupling which embodies the elen entsof simplicity, economy, durability, and

safety; and it consists in the particular condraw-head when onj curve. spective View of one of the draw-heads de-' tached from a car.

struction and arrangement of parts as will be hereinafter fully described and pointed out in the specification and claims, reference being Figure 1 is a perspective view of one end of a car, showing my coupling applied. thereto.

Fig. 2 is a central longitudinal view showing two draw-heads coupled together. Fig. 3 is a top plan view showing position of parts of Fig. i is a per- Fig. 5 is a top plan view of two draw-heads coupled together. Fig. 6 is a view showing a socket member for adapt- I ing the draw-head to very acute curves, showing in full and dotted lines therelative positions of the various parts when said couplingheads abut each other. Fig. 7 is a detail sectional view of thedraw-head B. illustrated in Fig. 6.

In the practical embodiment of my invention the draw-heads are arranged to interlock and be held together by thepin, and said drawefiected from the side of the car either on single casting. Said head portionB is formed with segmental projecting pointsor members D and chambers B and lateral projections D straight or curved portions of the track.

These draw-heads, one of which is shown in detail in Fig. 4, consist of the rear wall or flanges E and the head proper, 13, formed of a the front faces of which are flat and form abutment-shoulders O O. The segmental projecting members D,of which there are,preferably, two or more to each head, have the front edges of their upper andlowerfaces beveled, as at d, and rounded to facilitate their interlocking movement as the heads come together. The

rear wall or flanges E of the heads are rigidly secured to the end sills of the car. The pro j ecting coupling members or noses D are each provided with an elongated pin-aperture D in width slightly greater than the diameter of the pin F, and said apertures extend rearwardly beyond the front faces of shoulders O on the projections D but not as far back as the rear walls of the chambers B. It will be observed by reference to Figs. 2 and 5 that the beveled edges d of the noses or members D do not act as bumpers or stops at all, the said beveled ends being held from engagement with the rear Wall E and the back wall of the chambers Bby the shoulders 0. As will be noted particularly in Fig. 5, such shoulders C will serve, as abutting or bumper portions to receive the full impact of the shock when the two cars come together, and as the pinapertures are elongated and as such elonga bers D, and thereby prevent any possibility of such ends engaging the back wall E or the back of the chambers or mortise B.

By arranging the several parts in the manner shown and stated it will be manifest from Fig. 3 that the cars can be coupled together on curves or will freely take curves.

InFi g. 6 is shown an arrangement by which very acute curves may be provided for. In such construction a socket member comprising a back-plate E and box B having the chamber or socket B and the pin-apertures D in the upper and lower Walls of said box, is secured to the car. The draw-head B is provided with a rearwardlyextending rounded lug B having an elongated-vertical aperture B therethrough to receive a pin F passed through the apertures D in the box B The front portion of the head is the same in construction as the previously-described draw-heads.

As a simple means for manipulating the coupling-pin from the sides of the car 1 conappear.

arm G, formed with a pin-guide G at its lower end, projected or extending from a rock-shaft G, journaled in bearings g on the rods of the car, said rock-shaft being so mounted as to be capable of longitudinal movement in its bearings, so that the pin may be moved to one side of the draw-head when not in use or when the cars are being shifted or"bunted. By forming the arm G with the pin-guide G which has an open slot at its lower end to embrace the pin F below its head, it serves to be raised to guide the pin, hold it in a steady position, and keep it from moving when raised.

From the foregoing description, taken in connection with the drawings, the advantages of my improved coupling will immediately It will be noticed that the coupling operation can be effected with absolute safety, as no one is required to go between the cars. As no links are necessary, the expense of equipping cars with my device will be lessened, and in the forms illustrated in the first five figures of the drawings only one pin at position, and dips in the track which would cause small cars to pitch up and down are provided for and accommodated. It may be sometimes desirable to apply the draw-head to the carin a different manner from that shownfor instance, the draw-head may be provided with a rearwardly-extending hollow neck, the rear wall of which is provided with an opening through which a headed draft-pin is passed, the other end of said pin being held in place as usual by a spring key passed through it.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is Y 1. In a car-coupling, a draw-head comprising a body portion having one or more forwardly-projecting horizontal coupling members or noses, laterally projecting flat-faced shoulders at the base of said members on each side thereof, said coupling members provided with elongated apertures.

2. In a car-coupling, a draw-head comprising a body portion and a rear wall adapted to be secured to the sill of a car, said body portion provided with a plurality of forwardlyextending segmental coupling members and chambers to receive said members, lateral abutment-shoulders having their front face vertical and flat and projecting from the base of the coupling members on each side thereof, said coupling members having elongated vertical apertures extending rearwardly of the front face of the abutmentshoulders, the chambers in each draw-head being of greater length than that of the coupling members from the front face of the abutment-shoulders to the front edge of the said coupling members.

3. An improved car-coupling comprising a draw-head consisting of a plurality of horizontal forwardly-projecting coupling members or noses having their front edges beveled and provided with elongated vertical apertures therethrough, lateral shoulders at the base of said members having their front face vertical and flat, outwardly-projecting flanges at the rear of said draw-head, said head provided with chambers or mortises to receive the coupling members, and a detachable pin.

4. An improved car-coupling comprising a draw-head formed at the top and bottom wall with horizontal coupling members, the front edges being projected at the sides to form abutment-shoulders and having elongated pin-slots in the said coupling members extended rearwardly beyond the abutting edges, a pin loosely held in such slot-s, said abutment edges and coupling members being arranged relatively as shown whereby the pin will be relieved from strain as the cars come together, and the front edge of the coupling members willbeheld from contacting or striking against each other, and whereby the entire impact or push force will be received on the abutmentshoulders.

5. In a car-coupling, the combination with a draw-head provided with a plurality of horizontal forwardly-projecting coupling members, and laterally projecting abutmentshoulders at the edges thereof, said coupling members having elongated pin slots, of a rock-shaft mounted on the end of a car and having an outwardly-projecting arm, and a pinguide projecting downwardly and outwardly from said arm, and adapted to embrace a pin loosely fitting in the elongated slots in the coupling members.

6. In a carcoupling, a socket member adapted to be rigidly secured to the sill of a car and provided with vertical slots, a draw-head provided with a rearwardly-projecting lug having an elongated vertical slot therein, said lug adapted to be loosely held in said socket by a pin passing through the slots in said socket and lug, said draw-head provided with laterally-proj ectin g rear shoulders, forwardly-projecting front coupling members having elongated vertical slots therethrough, and laterallyprojecting abutment shoulders at the sides of said coupling members, whereby said draw-head will be adapted to accommodate itself to acute curves.
